Sažetak
Manita peć Cave (NP Paklenica, Croatia) is relatively small show cave (67, 510 m3, Kuhta, 2010) adapted for visitors in 1937 for its exceptional interior. Due to its morphology (descending channel) the innermost part acts as a 'cold pocket' having the mean annual air temperature (MAAT) of 9 °C (1σ=0.4 °C) in contrast to external MAAT of 13.7 °C (Surić et al., 2017). Given these settings and increasing number of visitors (mostly concentrated in the summer season), new monitoring campaign has been initiated in February 2018, aimed at the variation in cave air CO2 concentration. Measurements are conducted along the visitor path on monthly basis throughout the year, with occasional measurements before and after touristic groups. Winter cave air CO2 concentration is characterised with minimal spatial and temporal variations (325-464 ppm), while the summer situation is expected to be more unstable. Along with natural increase of cave air CO2 concentration due to diffusion of summer CO2-rich epikarst air through the bedrock discontinuities, short-term anthropogenic impact is also expected. Though, due to the cave morphology and relatively low number of visitors, variations are much less expressed than in nearby Modrič Cave (Sršen et al., 2018). References: Kuhta, K., 2010.
